Sagot :
Answer: 455 mph
Step-by-step explanation:
if train one is traveling one way at 60mph, then you have to multiply that by 3.5 to see how far it traveled in that amount of time.
60 x 3.5 = 210
then, you have to multiply 3.5 by 70mph, to see how far the second train has traveled in that amount of time
70 x 3.5 = 245
finally, since both trains are moving in opposite directions, you have to add up the distances together to get the final difference
210 + 245 = 455
Both the trains are in an opposite direction. after 3.5 hours they will be apart from a distance of 455.
What is speed?
Speed can be calculated as the ratio of distance traveled to the time taken.
Speed x time = Distance
Two trains start at the same point at the same time and simultaneously travel in an opposite direction.
we need to find that how far apart will they be 3.5 hours.
The speed of the first train is 60 mph
Speed x time = Distance
= 60 x 3.5
= 210
The speed of the second train is 70 mph.
Speed x time = Distance
= 70 x 3.5
= 245
Since both trains are moving in opposite directions, we have to add up the distances together to get the final difference.
210 + 245 = 455
